"The U.S. Environmental Protection Agency is demanding answers to dozens of long-standing questions about the handling of wastes contaminated with polychlorinated biphenyls, PCBs, at U.S. Army ammunition production facilities nationwide.

Activities at 28 closing Army ammunition production facilities with a total of number of more than 16,000 buildings and structures could be affected.

In a July 7 letter to the Army, the EPA asks for a detailed response to questions about the status of demolition of buildings, management and storage of PCB wastes, research on destruction or removal of paint, and operation of decontamination ovens.

Army facilities that the EPA has identified as having PCB contamination include the Badger Army Ammunition Plant in Wisconsin, the Sunflower Army Ammunition Plant in Kansas, Iowa Army Ammunition Plant, Cornhusker Army Ammunition Plant in Nebraska, as well as the Kansas Army Ammunition Plant and the Ravenna Arsenal in Ohio."
